Six-year study examines impacts of fescue and symbiotic fungus The popular forage and turf grass called tall fescue covers a vast amount of land in the U.S. -- an area that's estimated to be larger than Virginia and Maryland combined -- and a new study by ecologists at Rice University and Indiana University suggests there is more to fescue than meets the eye. Results of the six-year study, which are available online in the Journal of Applied Ecology, show that a symbiotic fungus living inside...

One hundred million years ago the earth looked very different from how it does today. Continents were joining and breaking apart, dinosaurs were roaming the earth, and flowering plants were becoming more widespread. The southern hemisphere supercontinent known as Gondwana formed around 180-200 mya during the breakup of Pangaea and then began to split apart about 167 mya. As scientists reconstruct the history of these land masses and life during this period, many questions arise. For example,...

Researchers from the Biotechnology Foundation Laboratories at Thomas Jefferson University have identified a way to increase the oil in tobacco plant leaves, which may be the next step in using the plants for biofuel. Their paper was published online in Plant Biotechnology Journal. According to Vyacheslav Andrianov, Ph.D., assistant professor of Cancer Biology at Jefferson Medical College of Thomas Jefferson University, tobacco can generate biofuel more efficiently than other agricultural...

Superior 'leaf plumbing' gave flowering plants evolutionary advantage To Charles Darwin it was an 'abominable mystery' and it is a question which has continued to vex evolutionists to this day: when did flowering plants evolve and how did they come to dominate plant life on earth? Today a study in Ecology Letters reveals the evolutionary trigger which led to early flowering plants gaining a major competitive advantage over rival species, leading to their subsequent boom and abundance. The...

Plants don't mind sharing space with their kin but when they're potted with strangers of the same species they start invigorating their leaves, a study by McMaster University reveals. The research, which appears in the current issue of the American Journal of Botany, suggests non-kin plants will not only compete underground for soil nutrients, but will attempt to muscle out the competition above ground in the ongoing struggle for light. It follows previous research from McMaster University...

Ability of jewelweed to recognize 'relatives' from 'strangers' helps shift resources for growth The concept of altruism has long been debated in philosophical circles, and more recently, evolutionary biologists have joined the debate. From the perspective of natural selection, altruism may have evolved because any action that improves the likelihood of a relative's survival and reproduction increases the chance of an individual's DNA being passed on. Social behavior, kin recognition, and...

Light manipulation technique effective, environmental alternative for growing holiday favorite Poinsettias can be a lucrative crop for ornamental plant growers, particularly during the Christmas season. In the temperate regions of the southern hemisphere, where poinsettias are grown for both export and local markets, high-demand time for holiday sales occurs during the summer, when warm temperatures and stronger light can accelerate plant growth, often resulting in unmarketable plants. To...

Plant quality and size affected by touching, body lotion African violets have a mixed reputation. Their delicate, colorful flowers and furry, soft leaves make them a favorite among home gardeners and growers. But the striking plants are often regarded as temperamental: a precise recipe of light, moisture, warm temperatures, high humidity, and fertilizer is required to encourage African violets to grow and flower. A recently published study by scientists Julia C. Brotton and Janet C. Cole from...

If past is prelude, trees and shrubs may have a harder time keeping pace with global warming Can we predict which species will be most vulnerable to climate change by studying how they responded in the past? A new study of flowering plants provides a clue. An analysis of more than 5000 plant species reveals that woody plants "” such as trees and shrubs "” adapted to past climate change much more slowly than herbaceous plants did. If the past is any indicator of the future, woody...

Dawsonia
2013-11-04 10:01:23

Dawsonia is a classification of mosses. This genus is a member of the Polytrichaceae family. Dawsonia plants are commonly known to grow taller and have thicker leaves than other common mosses. Mosses are known to grow when hydrated, however most common mosses lack cuticles and internal transport tissues. This makes it difficult for them to maintain substantial amounts of water and they typically do not grow tall. Dawsonia are an exception to this common rule. Dawsonia mosses are...

Petrified Forest National Park

Petrified Forest National Park is located in the state of Arizona in the United States. The park holds 221,552 acres of land, of which 50,260 acres are comprised of a designated wilderness. The area was once inhabited by Native American tribes including the basket maker and pueblo peoples. The first American explorers to enter the area arrived while searching for good routes leading from east to west. This group, led by Army Lieutenant Amiel Whipple, surveyed the northern area of the...

The Whisk Fern (Psilotum nudum), is a genus of fern-like vascular plants, one of two genera in the family Psilotaceae, order Psilotales, and class Psilotopsida (the other being Tmesipteris). The distribution of Psilotum is tropical and subtropical, in the New World, Asia, and the Pacific. The highest latitudes known are in South Carolina and southern Japan for P. nudum. In the U.S., one species is found from Florida to Texas, the other in Hawaii. They had traditionally been thought not to...
